Section 12: Site Area Calculation

Chapter 4 Tera Calculation 2_Distribution Center Size Calculation

When incorporating a building into the site layout, securing a route for trucks (truck turning corridors) is required in addition to the building coverage ratio and floor area ratio.
Incoming berths are often used for large trucks, while outgoing berths are used for small trucks, but there tends to be a need for a larger number of berths. The 
minimum required truck passage (effective width) = truck turning corridor + 1 m. In addition to truck passageways, the site also has legally designated green spaces such as car and bicycle parking areas and truck waiting spaces. It is particularly important to ensure a safe route for people (large centers have a total of more than 500 people passing through) that avoids interference with trucks.

 Item 1: Building Ratio/Floor Area Ratio



The building coverage ratio varies depending on the zoning (the area is divided into 13 regions according to use to form planned urban areas ). There are some areas where construction is not possible, so please check other works. The calculation is: building coverage ratio = (building projected area + eaves area * 50% ) / site area, floor area ratio total floor area (virtual floor added) / site area. Tera settings are calculated using a building coverage ratio of 60 % and a floor area ratio of 200% .
